ABSTRACT:
In a system for processing a plastic web plural work stations are disposed on an elongated beam. The web is provided with positioning holes cooperating with complementary pins in at least one work station. As the distance spacing allocated holes may vary due to shrinking, the beam may be bent about a transverse axis into a ring sector shape thereby adapting the pin distances to the actual hole distances.
